Detection method:
Before you dig the treasures, the following must be taken into account:
1 Frequency adjustment
2 The intensity of the tone
3 The duration of the sound
4 Offset of the indicator
5 Conductivity data
In the detection, the tone of the tone changes, is the first signal symbolizes the presence of metal objects in the excavation, these factors must be taken into account, but also rely on personal experience. Detection, the intensity of the tone issued, The larger the volume of the object, the change in sound and the deviation of the pointer are occurring at the same time, so that people can better analyze and find the object. After the intensity of the sound and the offset of the pointer determine the size of the object, the object may be shaped Can know, through the understanding of the conductivity of the object and the identification of metal species.If you want to identify the type of metal, we must choose DISC This file, after re-tuning the frequency of this file, press RESET Button 3Seconds, you can detect the.
PULSE AR III There is a metal recognition function, and it is inserted inside the micro-processor can estimate the conductivity of the metal, so it does not need to spin the disk. This improvement to improve its detection depth has a great effect.
In the case of detection, if the tone is weak, it can be ignored. The conductivity of the metal is estimated, which requires that if the detection of metal, it will make the tone of high-intensity, as long as the location of the disk just buried in the treasure The top of the conductivity coefficient will be stored and displayed in the header.
We recommend that you detect the time, first transferred to it ALLM This file, hear the tone is stable, strong enough after the transfer to it DISC This file.
Keep the pan at a level that is stable from the ground RESET Button 2Seconds. Then the plate is removed, repeat the above action until the sound reaches the strongest, DISC The light of the diode will be bright and the meter will show the conductivity of the metal.To compare the metallic conductivity indication with the metal value indication, its main purpose is to determine the type of metal.
The value of the metal is indicative of the approximate value of the metal, which you can judge by your own probing experience.
For example, one 10cm *10Cm of iron plate, its value data is 50A piece of gold plate of the same size, its value data is 40, If it is a silver plate, it shows the value of the data in the header 30As the shape and size of the object change, the value data shown in the header changes, depending on your experience.
Note: To ensure that the displayed conductivity data is correct, you must press each shift RESET Button.
Error signal recognition:
In the detection process, due to the diversity of filters and regulators, and some will interfere with it, will affect the instrument to determine the value of the metal.
1. In the magnetic oxide of the soil, it shows the first conductivity of the coefficient will be wrong.
2. Very large pieces of iron will be mistaken for precious metals.
3. To determine the type of metal, then the size of the metal to achieve 5cm *5cm
4If the composition of the two metals is close, there may be false positives
5Radio transmission can also interfere with the instrument
6A strong magnetic field, especially a high - volt antenna, can interfere with the instrument
The first change in sound implies the presence of metal objects.
The stronger the alarm sound intensity, indicating the greater the volume of buried objects.
Precautions:
This instrument is suitable for a large range of search for large, deep buried objects.
If you want to search for a large object, it is necessary to use a large exploration disk, to search for small objects, use the small probe plate size will be the size of the change with the probe automatically adjusted.
The instrument is equipped with conductive micro-processor, such as iron, gold and silver, etc., it can identify, and in the header through the pointer to the different data to tell people the type of metal.

Instructions

Detection of metal

1. Select the probe (or cylindrical probe, 1m? M detection frame) to be used as necessary. Connect the plug of the signal cable to the signal cable socket on the back of the control box.
   CAUTION: Before connecting the plug of the signal cable, you must turn off the power to the control box.
2. Set the power switch to 'ON' to power on.
3. To adjust the ground:
   Choose a metal-free ground to keep the probe from the ground by about 5 cm (when using a 1m m detection frame,
   20 to 50 cm, depending on the height of the detection frame from the ground when the metal is detected), turn the 'volume' knob to get the appropriate
   Press the 'Reset' button twice to release the 'Frequency' knob until the speaker emits an audible "click, click, click ..." sound (similar to a mechanical stopwatch) Of the minerals on the probe plate to eliminate the impact.
   Note: In the detection process, because the detection area of ​​the soil condition is poor or affected by geomagnetic, instrument sound becomes unstable, the need to re-balance adjustment.
4. In the detection process, keep the distance between the detection disk and the ground about 5 cm (1m? M detection frame from the ground about 20 to 50 cm)
   When the metal is detected, the frequency of the instrument's 'despatch, despair, despatch ....' sound will increase depending on the size of the metal object detected,
   The number of detection signals in the lower left of the LCD screen will increase.

Metal type identification

According to the different metal conductivity difference, the instrument has the ability to distinguish metal type, but this requires detection of metal area can not be too small, weak detection sound is not able to distinguish.Only when the detected signal strength, control panel Of the 'power / alarm' LED by
When the green light turns red, the instrument can tell the metal type.

Press the 'Reset' key for about 2 seconds and release, then move the probe to the top of the metal,
/ Alarm 'LED turns red, the small arrow on the top of the LCD (ie, the metal conductivity indicator icon) indicates the conductivity of the detected metal
The ratio of aluminum, copper, lead ≤ 30%, iron ≤ 60%, gold> 80%. This is only a reference value, to accurately determine the type of metal, but also
Such as: a 10 × 10 cm of iron, indicating the value of 50%, the same size of gold, indicating the value of
60%, the same size of silver, indicating the value of 100% .When the metal size and shape changes, the indication value will change, at this time, must be empirically to identify the metal object.In summary, the instrument conductivity Indicators affected by many factors, not necessarily correct, for reference only
test.
Note: The scales 2, 4, 6, and 8 above the metal conductivity indication icons represent 20%, 40%, 60%, and 80%, respectively.

* The AR5 has a maximum detection depth of 16 meters when conditions are met
